The trigger is provided with aspring and a spring notch of any kind to be held "onthe one hand in a position ready for operation, preferably retaining a pressure or tension point, and on the other hand in the locked position.

To 'bring the trigger 8 into the lockedpo sition 1 it is pushed forwardly by the forefinger of the V In a preferred embodimentof the invention the control lever together with the pivot for the trigger and the locking lever is bent forwardly to hand steering the aircraft, whereby, after overr coming aresilient obstacle the trigger isfmoved] rearwardly intoengagement with a; stop l0 lava "surround thepivot 6 of the trigger 8.

spring (Fig. 3) presently to be described. The trigger is so formed as to easily fit the knob of the handle in its locked position so that the handle may also. be grasped from above. As the A button 9 is arranged in the notch I it is perfectly safeguarded when the trigger 8 is thrown backwardly into the lockedposition. i

To bring thetrigger Bout of its locked position into the position ready for operation it is turned forwardly by the forefinger of the hand actuating the device. For this purpose the edge of the trigger 8 is so formed as to stand farenough away from the handle. Preferably the handle may also be provided with a depression I renow in Fig. 1 in dotted lines into which the forefinger can slide to safely grasp the trigger 8 from below. If the handle is constructed to be operated by effecting the various positions of'the trigger, may ,be replaced by other well known means.

Moreover, the releasing device according to the invention also may be used for operating other apparatus, i. e for light or sound signals, for taking photographic pictures or the like.

the right hand the depression l2 occupies the? position shown in dotted lines, i. e., is provided on the side of the drawing turned away from the" observer; From Figs. 1 and 2-it is'evidentthat when the trigger 8 is swung downwardly into the position ready for operation, the handle I may unimpededly and tightly begrasped without fear of premature firing of the" gun. For firing the forefinger must be lifted out of the depression 5 so that the trigger 8 may be grasped by the foreton i3 occupies -,a position mostfavorable for actuating by the thumb of the right hand. Fig; 1 shows the manner in which the press button I3 is prevented from unintended operation by the trigger 8 which is in itslocked position, Fig. '2 shows the position of the trigger 8 ready for operation and the unlocked press button I3.

In 'Fig. 3 a detail of the construction according to the invention is illustrated showing the spring and the spring notch. arrangement actu-- ating the triggerB. The windings of spring l4 One. end I5 of spring I4 bears against the handle 'I. The other end l6 'of spring l4 grasps the trigger Sand tends to swing the latter forwardly until a cam l I provided upon its hub contacts the ball l8. The ball I 8 is resiliently mounted in a guide,the spring 2|] being employed for. urging the ball outwardly in its guide and toward the handle 8. If the trigger.8 is actuated,-first' of all only the resistance of the spring I 4 is to be overcome until the trigger abuts against the button 9. Striking ,of the trig 'ger against the slide member 9 results in a pressure or tension point, whereas further movement of the "trigger results in firing the gun] To bring the trigger 8 into its lockedposition .it is rotated in a clockwise direction for a certain amount under the influence of the spring-pressed ball I8.
